The decay of a neutron within a nuclide is illustrated by the decay of the carbon isotope carbon-14, which has 6 protons and 8 neutrons. With its excess of neutrons, this isotope decays by beta decay to nitrogen-14 (7 protons, 7 neutrons), a process with a half-life of about 5,730 years. [37] Nitrogen-14 is stable.
In nuclear astrophysics, the rapid neutron-capture process, also known as the r-process, is a set of nuclear reactions that is responsible for the creation of approximately half of the atomic nuclei heavier than iron, the "heavy elements", with the other half produced by the p-process and s-process.
Neutron radiation is a form of ionizing radiation that presents as free neutrons.Typical phenomena are nuclear fission or nuclear fusion causing the release of free neutrons, which then react with nuclei of other atoms to form new nuclides—which, in turn, may trigger further neutron radiation.

The values of the neutron drip line are only known for the first ten elements, hydrogen to neon. [19] For oxygen (Z = 8), the maximal number of bound neutrons is 16, rendering 24 O the heaviest particle-bound oxygen isotope. [20] For neon (Z = 10), the maximal number of bound neutrons increases to 24 in the heaviest particle-stable isotope 34 ...
A chart or table of nuclides maps the nuclear, or radioactive, behavior of nuclides, as it distinguishes the isotopes of an element.It contrasts with a periodic table, which only maps their chemical behavior, since isotopes (nuclides that are variants of the same element) do not differ chemically to any significant degree, with the exception of hydrogen.
[51] [52] GW170817 therefore confirmed neutron star mergers to be viable sites for the r-process, where the nucleosynthesis of around half the isotopes in elements heavier than iron can occur. [8] A total of 16,000 times the mass of the Earth in heavy elements is believed to have formed, including approximately 10 Earth masses just of the two ...
India-based Neutrino Observatory (INO) is a particle physics research project under construction to primarily study atmospheric neutrinos in a 1,200 meters (3,900 ft) [1] deep cave under INO Peak near Theni, Tamil Nadu, India.
